What Is Indigo?

Indigo is a natural dye that is obtained from the plant Indigofera tinctoria. It’s rich, dark blue in color and is mainly used for dyeing clothes, especially denim.

How To Use Henna And Indigo To Color Your Hair Black?

Step 1: Applying Henna

1. In the mixing bowl, combine the henna powder and lemon juice.
2. Slowly start adding water and stirring this mixture until you have a thick pudding-like paste.
3. Cover the bowl with a plastic wrap and leave it on overnight for the dye in the henna to release.
4. Working with one section at a time, start applying henna with a hair coloring brush right from the roots to the ends.
5. Roll this section around your finger into a little curl and stick it to your head.
6. Once you’re done with applying henna to all the sections, apply the rest of the henna all over your head and work it in with your hands for complete coverage.
7. Put on a shower cap.
8. You can leave in the henna for anywhere between 2 hours and overnight.
